RADIATOR V. E. FLODIN REAMING, FACING, AND TAPPING- MACHINE 19 Sheets-Sheet l 9 Filed March 19, 1930 Patented Feb. 14', 1933 VICEQR FLODIN, OF OAK PARK, ILLINOIS, ASSIGNOR TO CRANE 00., OF CHICAGO,

This invention relates to machines used in nufac'ture of radiators and more particularly to a machine for reaming, facing and tapping the connecting portions of rad'ator sections which are to be secured tor to make up a radiator. \oan lete radiators are made up of a pluraiitv (if sections joined together to provide i diator of given heating capacity in accordance'with the size of the space to be The sections are connected together or continuous flow thcrethrough of the heatmg fluid by means of openings or passages through each end of the radiator sections. Generally these openings are threaded to receive right and left nipples which serve to connect the openings, and draw and hold together the sections. A gasket is usually i iced between the abutting faces of the raor sections.

s apparent that the connecting openings through the radiator sections must all be uniformly and accurately reamed, faced and tapped particularly if the sections are to be le in quantity and radiators made up from stocks of suitably sized sections. The above mentioned oper tions must be made rapidly and with as lit le handling by operators as possible if the radiator sections are to be made in quantity and economically. It is to these finishing operations singly and collectively that this invention relates.

it is the purpose of this invention to provide a single machine which will ream, face and tap a radiator section and which is autoand continuous in operation.

nut-1c l; is also the purpose of this invention to provide such a machine which will ream, face and tap both connecting openings of a radiator section and which also will operate upon a plurality of sections simultaneously.

it is also an object of this invention to provide such machine which will operate upon various sized radiator sections.

Q. ccording to this invention a dial type machine is provided in which a plurality of radiator sections are arranged radially around the and moved consecutively through a cycle comprising a series of operations perform-ed at a series of positions, i. e., at each 1930. Serial No. 437,206.

position a certain operation is performed by suitable tools. The tools are moved into and out of operating position while the radiator is rigidly held and accurately located at each of the prescribed positions. A suitable numher of tools are provided and arranged whereby both sides of both ends of the radiator are operated upon simultaneously thus elimlnating the necessity of removing the radiator The dial is provided with means for securing a plurallty of radiator sections in eX- actly located positions in order that uniformity and accuracy is obtained in finishing each radiator section. Positive means are provided for rotating the dial to the various positions and additional means are provided for rigidly and accurately locating and looking the dial in each of the operative positions. Means are further provided in connection with various features of the machine that should any one part thereof fail to function in the proper manner the entire machine automatically will be stopped.

A better understanding of the novel features, advantages and construction of this invention will be had from the following detailed description given in connection with the drawings illustrating one form of this invention and in which:
